Learn how to make a touchless air drum set using Arduino and ultrasonic sensors for endless musical fun. ‘That Has Never Been ...

This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

When using an ultrasonic sensor component in ESPHome, setting the timeout value with two decimal places causes the sensor to continuously time out, even when the target distance is well within range.

Abstract: During orbital operation, the space plasma environment affects the spacecraft, leading to the occurrence of electrostatic discharge, which can jeopardize the safe operation of the spacecraft ...

Abstract: In this paper, an innovative ultrasonic nondestructive testing (NDT) method is proposed, which combines multimodal sensor fusion technology with deep learning algorithms to address the ...
